Both a and b A polar molecule is least likely to interact with: A) Water B) A Carboxyl Group C) A Hydrocarbon D) An alcohol group E) A Carbonyl group

Explanation / Answer

6) hydrogen bonds are the bonds are the bonds between two water molecules. All molecules have covalent bonds but only some molecules have hydrogen bonds so answer is "C"

7) Amino acids are organic compounds containing amino (-NH2) and carboxyl (-COOH) functional groups.along with a side chain (R group) specific to each amino acid. So answer is "D"

8)The cohesive forces among liquid molecules are responsible for the phenomenon of surface tension. So answer is "B"

9) the specific heat is the amount of heat per unit mass required to rise the temperature by one degree celsius.the relation ship between heat and temperature change is usually expressed in the form shown below where c is the specific heat. So answer is "A"

10) WATER is a good example of a polar molecule the oxygen atom attracts electrons much more powerful than the hydrogens so answer is "A"
